ABSTRACT:
A quick-release connecting apparatus for detachably interconnecting two objects includes male and female structures respectively attachable to the objects. The female structure has a generally U-shaped receptacle formed therein which opens at a peripheral edge thereof, the male structure has a stud projecting therefrom with a part-circular head at its distal end with a straight side which is dimensioned to be received in the receptacle from its open end and being rotatable about the axis of the stud while disposed in the receptacle. A retaining prong is unitary with the female structure and is flexibly and resiliently movable between a locking position projecting into the entrance of the receptacle and a release position out of the entrance. The stud head moves the retaining member out of the way upon insertion into the receptacle to permit insertion in any orientation, but the retaining prong prevents removal of the head from the receptacle except when it is in a single orientation wherein the straight side faces the pawl. A flexible, resilient bias finger integral with the female structure projects into the receptacle for resilient engagement with the head to inhibit rotation thereof while in the receptacle.
